- and exact description.

The invention relates to snow-plows and designs more particularly toprovide an improved plow or plowing attachment which may be mounted upona motor-vehicle to remove the snow from an uneven street.

One object of the invention is to provide an improved plow which isparticularly adapted to be operated over a pavement or road and in whichprovision is made for causing the plow to ride over obstructions and toadapt itself to uneven road-surfaces.

Another. object ofthe invention is to provide an improved plow which maybe attached to a motor-truck of usual construction so that the plow maybe employed as an attachment to the truck and so that the truck maybeused to operate the plow to remove snow from the road. Lastly theinvention designs to provide a snow-plow of improved construction.

Theinvention consists in the novel features hereinafter set forth andmore particularly defined by claims at the conclusion hereof. lnthedrawings: Figure 1 is a side elevation of a motor driven truck embodyingthe invention. Fig. 2 is a side elevation of a portion of the plow,showing in dotted lines, different positions which one of the plowsharesmay be caused to assume. Fig. 3 is a horizontal section through theplowshare, the springconnections for the adjustable sliare'being shownin elevation. Fig. 1 is a vertical section on line 4-4 of Fig.1. Fig. 5is a section; on an enlarged scale taken on line 5-5 of Fig. 4. Fig. 6is a detail section showing the device for securing the rear-ends of theside rails of the plowrsupporting frame to the side-rails of thetruck-frame- Fig. 7 is a detail perspective showing the manner in whichthe plow frame is secured to the front of the-motor truck frame.

The improved snow-plowing mechanism is adapted-to be attached to amotor-vehicle f s al estr e on n ment ar ying wheels at, traction-wheelsh, a frame a,

a seat d and a'radiator e, as Well understood in the art.

The plowing attachment comprises a fixed share 12 which is inclinedrelatively to the lines of travel, and has its lower edge disposed asuiiicient distance above the ground, so that it will clear anyobstructions on the road, The upper and lower edges of share 12 arecurved and the inclination of' the share is such as to deflect the snowin its path, to one side of the vehicle. A supplemental and movableshare 13 is adjustably sustained so that it will adapt itself to unevenportions of a roadway, is also inclined ,to the line of travel of thevehicle and has 4 its lower edge disposed to Work below share 12, and inclose contact with the ground, so that this share willfollow the fixedshare and throw the snow nearest to the ground or that over which share12- passes, to one side of the vehicle. Both shares 12 and 13 aresustained by a supporting-frame which is adapted to be attached to andremoved from the vehicle-frame 0 and comprises side-bars 14: which havetheir front ends bent downwardly and rigidly secured to brackets 15 onthe back of share. 12. The rear ends of side-bars 1st of this detachableframe are Secured in blocks 16 respectively, which are adapted to restagainst the sides of the frame (2. Each block 16 has secured thereto, bythe bolts 17, a. clip 18 which is adapted to fit against the under sideof one of the side rails of frame 0, and has a groove 19 which isadapted to receive the base flange on said rail. A lug 20 secured toblock 16 by bolts 21 is extended laterally to overlie andfit against thetop of said rail and has a groove 22 in which the top-flange of saidrail will fit. Bolts 60 and a. hook-plate adapted 'to engage the frontrail of the truck-frame, serve to detach-ably secure the central portionof cross-bar'23 to the truckframe. These attaching-devices serve torigidly secure the rear end of rails 14 of the plow-supporting frame tothe side-rails of the truck-frame a, without the necessityof weakeningor drilling said rails. By removing the clips 1-8and lugs 20 the rearends of side-bars 14 may be disconnected from the truck. i The.plow-supporting frame also comprises a cross-bar 23 which is adapted tolilfi 5 33 will 'be vertically slidable therebetween.

extend over the front end of the truck-frame in front of the radiator c,and has downwaidly extending members or uprights 24 plow-supportingframe is secured to the- .front end of the truckframe, by blocks 27integrally formed therewith. These uprights are rigidly secured toside-bars 14 by plates and 26. The front end of the which fit incornersbetween theuprights 24 and cross-bar 23 and are adapted to it againstthe outer sides of the truck frame, and plates 28 which are bolted tosaid blocks are adapted toengage the underside of the truck frame. Bydisconnecting the rear ends of'side-bars 14 from the truck frame andreleasing or removing plates 28 the plow sup orting frame may bedetached from the 3 cured to uprights"24 and serve to confinetruck-frame. v

Braces 29 extend between, and aresecured to, the lowerportionf'ofsuprights 24' and side-bars14xand secure the lower ends ofvthe uprights against backward stresses.

The adjustableplow-share 13 is pivotally sustained by aro'd 30 whichextends through lugs 31 secured to the back of said share and forwardlyextendingarms'32 on uprights 33, which are slidably mounted in waysformedbetween uprights 24, and plates 26 and 25 and side-bars 14. Plates34 are sethe lower portion bfup'rights 33 against outwardmovement andthe front ends of braces "29 are extended along the inner faces of theseuprights respectively, so that uprights At each side, plow share 13 isyieldingly held in operative position by a device for I pressing it intosuch position, and which permits the lower portion of said share toswing or tiltbackwardly when an insurmountable obstruction is met withEach of these devices consists of a rod'36 which has its front endpivoted in lugs 37 secured to the back of share 13 near the lower edgethereof, a spring 38 coiled around said rod and engaging a nut 39 whichis screwthreaded thereon, a bracket 40 secured toa the lower end ofupright 25 and through limiting the action'upon the share by the whichrod 36 is loosely extended, and nuts 41 which are screw-threaded to therear ends of the rod and serve as adjustable stops for spring. Byadjusting nuts 39, the tension of the springs may be varied.Consequently, when an obstruction is encountered, the

'- plow-share will be tilted backwardly by the obstruction as indicatedby the dotted lines in Fig. 2. Each side of the share 13 is verticallymovable independently of'the other,

so that in driving over an uneven roadway or when share 13 has beeiitilted backwardly against the force of springs 38- and the obstructiontends to raise the share, either or both sides of the share may beraised by the obstruction. For this purpose a springlever to tilt.

pressed device is applied to'each upright 33.- Each of these devicesconsists of a rod secured to the inturned end of the upright.

and extending through one end of alever 43, nuts 44 on'the upper end ofsaid rod, a coiled spring45-between the lever and the upper end ofupright 33 and another coiled spring 46 between the lever, and the nuts44. Lever 43 is centrally pivoted as at 47 to a collar 48 which isscrew-threaded to a vertical rod 49 having a hand-wheel at its upper endwhereby the rod may be turned to raise and lower the collar. The lowerend of this rod is swiveled in a suitable bearing 51 which is'formed ofsections and permits the head 52 on the lower end of the rod to berotated, but holds the rod against vertical movement. This constructionpermits either of the uprights 33 to slide upwardly in response tounevenness of, or obstruction on, the road.

The pressure of the share 13 on the road may be regulated by adjustmentof collar-48 which will, through the spring-connections with theuprights respectively, raise and lower them to correspondingly adjustshare 13. When one side of the share 13 is raised by a small obstructionon the rod, the upright 33 on that side will raise against the force ofspring 45 applied thereto and tilt or tend to tilt lever 43 against thespring 45 at the opposite side, which will permit the As soon as theplow has traveled over any unevenness the share 13' will be c'aused toassume its former relation in contactwith the ground. When anobstruction is encountered, which would otherwise arrest themachine,'share 13 will swing backwardly against the forceof springs 38.and the share will be curved rearwardly and downwardly to such an extentthat it will be deflected upwardly by the obstruction against the forceof springs 45. In this manner obstructions will not wreck theplowing-mechanisrnand the share 13 may be used to closely scrape theground without danger of breakage and without requiringfrequent'manipulation upon the art of-the operator. It will be understoothat the pivotal points of the pivotal connection are construction. Italso provides a share which may be operated to scrape the-ground andwhich will yield responsively to obstructions and inequalities of theground, without danger of breaks. v

The invention is not to be understood as restricted to' the details setforth, as these may be modified within the scope of the appended claimswithout departing from the spirit and scope of the invention.
